The illustrated embodimentoftheinven- 'tion: is described 5 as follows :.The; cook has the valve shell or bodyil, imwhiclris received:

a longitudinally,movable valve 2 controlled by the float. The float is attached to the lever 20, secured in the arm 21 of the bell crank lever 22, pivoted at 23 on the ear 24, which is projected upward from one side of the valve shell or body 1. The other arm 25 of the bell crank lever is connected by a link 26 with the lever 27, pivoted at 28 on a second sulear 29, projecting from the side of the valve shell or body 1. This lever 27 is received in a hole in the valve 2, and when the water rises in the tank the float is lifted and the bell crank lever 22 is turned to depress the valve 2 against the valve seat 3, formed on the upper end of the valve seat member 31, wvhich is screw-threaded into the valve shell or body. The valve body is supported on the pipe 32, which screws into the hole in the bottom of the valve seat member 31. This pipe 32 at its lower end screws into the ball cock support 33, which passes down through the bottom 34 of the tank and rests upon the packing washer 35, and is provided with a flange 36 which engages the packing washer and is clamped against it by the nut 37,

which is screwed on the outside of the ex-,

with a water passage surrounding ac tight joint with the bottom of thetank; The service pipe 39 is connected-by -v amnion-with" the SIIPPOl't-iIIlBHl-bfil':

But under abnormal conditions, that is to say, in places where the water pressure falls below normal, the valve 14 is unscrewed until the volume of 5 water flowing through the opening thereby made between the passage 10 and the outlet chamber 13 is large enough, together with the water flowing through the circuitous passage, to fill the tank within the required time.

of the ball cock of the patent to the present inventor dated April 18, 1916, No. 1,179,507. There is, however, this'addition to be made:

15 The construction lllustrat-ed in the said patent admits the by-pass water into the stream flowing through the passage 9 in such a way that as the valve 2 approaches its seat with some pressures of water, the water admitted the regulating valve 14: causes a di agreeable hissing sound. This it is theaspecial object of this invention to overcome and avoid. The outlet 13 of the said patent is an elongated opening overlapping two portions of the passage 9. In the construction herein shown, this outlet 13 is curved and delivers its water to the lower of the two portions of the passage 9, with the result that the hissing sound is prevented at all adjustments of the regulating valve 14.

lieved that the reason for this is found in the It is befact that the by-pass stream is directed straight against the side of themain stream passing through the main passageit), where 85 the by-pass stream strikes the main stream.

The valve bodyis provided on its front 2 side with aboss (Figs. 2 and 3) connected by the passage 4.1(Fig. 3) with the outlet chamber 13. A screw 42 is screwed into a threaded hole extending down'into the boss 60. Sometank outlet valves have no provision for refill of the closet bowl.- In such ;of the tank and thusbelow the outlet valve of the tank to the closet bowl. Theball cock valve is provided with the downfpipe 50, whichleads the water discharged by the out let 8down into the tank from the service pipe 35 'to 'thebottom of the tank so that its lower general, the operation of the ball cock above described is the same as the operation from the outlet 13.

end is most of the time submerged in the water in the tank. I

Having thus described the invention, what is claimed is:

1. A ball cock having, 1n combination, a

body having an inlet chamber and an outlet chamber, a main retarding flow passage connecting the inlet and the outlet, a valve seat located inthe inlet, a valve movable longitudinally in the valve body and adapted to press against the valve seat for controlling the flow of water in the inlet, an auxiliary or free-flow by-pass passage connecting the inlet chamber with the outlet chamber, the discharge end of the by-pass passage being located in the bottom of the outlet chamber, and means for permitting a portion of the water passing through the inlet to flow through the by-pass.

2. A. ball cock having, in combination, a valve body having an inlet chamber and an outlet chamber, a main retarding fiow passageconnecting the inlet chamber and the outlet chamber, a valve movable in the valve body forcontrollin-g the flow of water through the passage, an auxiliary or free-flow by-pass passage connecting the inlet chamber and the outlet chamber, having its discharge end opening into the outlet chamber at the upper end of the retarding flow passage, and a valve for regulating the flow of water through the bypass operating when opened Wider with decreased water pressure to shorten the valve operating time.

In testimony whereof I have'signed my name to this specification. i
